Unusual ergodic and chaotic properties of trapped hard rods
Debarshee Bagchi, Jitendra Kethepalli, Vir B. Bulchandani +4
We investigate ergodicity, chaos and thermalization for a one-dimensional classical gas of hard rods confined to an external quadratic or quartic trap, which breaks microscopic int…
Finite temperature equilibrium density profiles of integrable systems in confining potentials
Jitendra Kethepalli, Debarshee Bagchi, Abhishek Dhar +2
We study the equilibrium density profile of particles in two one-dimensional classical integrable models, namely hard rods and the hyperbolic Calogero model, placed in confining po…
Heat transport in long-ranged anharmonic oscillator models
Debarshee Bagchi
In this work, we perform a detailed study of heat transport in one dimensional long-ranged anharmonic oscillator systems, such as the long-ranged Fermi-Pasta-Ulam-Tsingou model. Fo…
Polyelectrolyte solution under spatial and dielectric confinement
Debarshee Bagchi, Trung Dac Nguyen, Monica Olvera de la Cruz
Polyelectrolytes under confinement are crucial for energy storage and for understanding biomolecular functions. Using molecular dynamics simulations, we analyze a polyelectrolyte s…
Energy transport in the presence of long-range interactions
Debarshee Bagchi
We study energy transport in the paradigmatic Hamiltonian mean-field (HMF) model and other related long-range interacting models using molecular dynamics simulations. We show that…
Fermi--Pasta--Ulam--Tsingou problems: Passage from Boltzmann to -statistics
Debarshee Bagchi, Constantino Tsallis
The Fermi-Pasta-Ulam (FPU) one-dimensional Hamiltonian includes a quartic term which guarantees ergodicity of the system in the thermodynamic limit. Consistently, the Boltzmann fac…
